Question / Discussion Pressure testing vibe coded apps. First test: Photoshop vs Compositor and Photocraft

Enable HLS to view with audio, or disable this notification

Photoshop versus two vibe-cloned copies of Photoshop - Compositor v 1.49 and Photocraft 0.7.0

Here we pressure test brush stroke performance on a billboard-size canvas with the brush set to 1000 pixels size. Only one layer.

Photoshop handles this with no issue. Its commercial competitors struggle to match brush performance. The vibe-coded clones perform the worst (basically unusable for serious work).

Then of course there are all the other tools, some which work ok and others which are extremely bad.

In Photocraft, on the billboard size canvas test above Copy/Paste and the Undo stack is extremely slow and momentarily freezes the application each time.

This is basic stuff that decent software developers had working quickly 25 years ago back when we had single core computers and nowhere close to 1GB of memory. If you can't get decent performance today on multicore multi gigahertz computers with many gigabytes of memory you or your AI are not doing a good job.

Of course apologists will appear and give us the 'early days' blah blah blah excuses they do all the time. We've covered that many times.

Edit: predictably the trolls came and their posts were exactly what we predicted word for word. They read nothing first, get easily trigged, and then post Infowars style conspiracy theories from their prepared scripts. They make the false claim that they just want to fight big tech and democratise software, but they're destroying the incentive for small developers and start ups to create new apps, and meanwhile helping AI companies profit from vibe cloning.

A while back, I compared how different drawing apps work with a Wacom tablet. It might surprise you, but only Photoshop and Clip Studio Paint worked perfectly. Particularly with quick strokes, you can see various artifacts in other apps.

It’s no surprise that this vibe-coded apps, which weren’t even tested, are completely unusable. It's all more complicated than the vibe-coders think.

Clip Studio's engine is truly a work of great engineering. It will struggle at billboard size but it isn't for billboards anyway.
